T 0 all whom 'it may concern:

Be it known that 1, ROBERT KELLER, a

citizen of the United States of America, re-

siding at Detroit, in the county of Wayne andState of Michigan, have invented certain new and useful 1m rovements in Bottle- Stoppers, of which t e following a specificatlon, reference being had therein to the accompanying drawings.

In pouring liquids from a bottle or other receptacle having a closure rovided with an outlet and air vent or air-in et, the stream is often intermittent or broken because of the resistance offered by the liquid at the inner end of the air inlet to the entrance of the air which must often bubble up from a considerable depth, the result being a splashing, surging, irregular flow which it is diflicult to direct and control.

This invention relates to a closure for a bottle or the like provided with an air duct which insures a steady delivery of the contents of the bottle from the discharge opening.

The invention consists in the matters hereinafter set forth, and more particularly pointed out inthe appended claims.

Referring to the drawings, the figure 1s a view, partially in elevation and artially in section, of an uptilted bottle provided with a closure embodying the features of the invention.

In the drawings, 1 represents a bottle or like receptacle whose mouth is provided with a closure Whose body 2 seals the mouth either by frictional engagement or other preferred connection with the wall of the mouth.

As herein illustrated the body is a cork stop er having a central plug 4 of glass, Wood or tl fe like, which extendsup through the cork and is provided with a metal cap 3, adapted to set or screw on over the openings. The closure has an outlet 10 which is a duct through the body and. may have a pouring spout, lip or like directing device on the outside. An air duct 5 is likewise formed in the body, and its inner portion leads through a nipple6 or the like on the inside of, the closure. This nipple is connected to an inner tube 7 of suitable length to extend toward the bottom of the bottle or receptacle, by a joint which permits angular movement of the tube 7 in all directions. This joint comprises a length 8 of rubber tubing or like flexible material not corrodible by the contents of the bottle.

At the lower end of the tube 7 a float 9 is able material not-attached by the liquid in which it is 'to be immersed, or a cork or wooden lug may be used, as herein illus secured. Thismay be hollow, of'anysuittrated. t is of sufiicient buoyancyto float the tube and bring its lower or free end to the upper level of the liquid when the bottle or receptacle is tilted on its side for outpouring.

a consequence of this construction, the inner end of the tube is always carried either nearly or quite to the top of the liquid when decanting, thus insurin ingress for the air after-t iquid in the tube has been expelled by the first intake of air.

quiet, unimpeded e.

This permits the liquid to escape thereafter I in a quiet, unbroken stream whichis readily controlled and directed: It is-of value for use in ink bottles or the like, where there is special need that the outpour be regular and quiet and easily directed.

Obviously, the construction may be varied,

and I do not care to limit myself to any particular form or arrangement of parts.

I claim as my invention 1. A bottle stopper comprising an inelastic core, having a discharge duct and a vent extending longitudinally therethrough a ring of elastic material surrounding the lower.

portion of the core adapted to frictionally enof flexible tubing leading fromthe inner end of the vent, a piece ofinflexible tubing 'seto the free end of the flexible tube a float on the free end of the tubing, and an imperforate metal cap having screw-threaded engagement with the outer end of the stopper body.

3. A bottle stopper com rising an inelastic core provided with a discliarge duct and an air passage. extending lon itudinally therethrough having an exterior l outer endand a shoulder adapted to seat itself on the rim of a bottle mouth a bushing of elastic material surrounding the reduced portion of the core adapted to frictionally enga e the mouth of a bottle, an apertured nipp e on the core in which the air passage terminates projecting beyond the body of the stopper, an air'tube connected at its gage and seal the mouth of a bottle, a piece cured in the free end of the flexible tubing.

y screw-threaded inner end by a short piece of flexible tubing to the nipple, an axially apertured float secured on the outer'end of the air tube, and an imperforate cup closing over the outer end of the core having a screw-threaded flange engaging said outer end.

4. The combination with an ink bottle, of a stopper therefor consisting of an inelastic core provided with a longitudinal discharge duct and an air passage having an enlarged outer end provided with an annular shoulder adapted to seat itself on the rim of the bottle mouth, a bushing of elastic material secured concentrically on the reduced portion of the core adapted tofrictionallyengage the mouth 15 of the bottle, an apertured nipple in which the air passage terminates, a piece of flexible tubing connected to the nipple, avbulbous float centrally apertured to receive and be secured on the free end of the tubing, and 20 an imperforate ca having screw-threaded engagement with t e outer end of the core.

In testimony whereof I afiix my signature in presence of two witnesses.

ROBERT KELLER.
